My pet peeve is the crappy undersized wire that Saturn uses on the genuine?? Saturn brand block heater for the S series. The idiot junior engineer that spec'd the wire obviously had no experience with winter. They must have saved a fraction of a penny on the material cost which they then wasted on the fancy plastic flex wrap and plug boot that is also unusable in the cold. It is by far the most expensive (5. ?) block heater that I have ever purchased and is only available from Saturn. I was unable to find an aftermarket heater for this engine or an immersion type heater which I believe would be far superior. I do not know why an emersion heater was not designed for this engine and can only speculate that there was no thought of heating designed into the block casting and that there is not enough room for an internal element. Florida engineering. If anyone knows of an aftermarket immersion type heater please post The copper conductor is so thin that it breaks inside the insulation next to the molded plug. I think this is due to flexing when the plastic insulation is cold and hard. I have always discovered that the wire was broken after dark and at 30 below when I plugged in for a morning start. This has happened to me several times on two different cars. YMMV Happy trails
